The Supreme Court struck down federal limits on political party spending in coordination with candidates Tuesday, tearing out a 50-year-old barrier that kept parties handcuffed while outside groups ran wild—and giving challengers a clearer path to compete against entrenched incumbents.
The 6-3 ruling along ideological lines means political parties can now both coordinate with their candidates and spend unlimited funds on their behalf, a right that Super PACs and dark-money nonprofits have enjoyed for years. Justice Brett Kavanaugh wrote the majority opinion, striking down the coordinated expenditure caps Congress imposed in 1974 in the post-Watergate panic.
The Republican campaign arms—the NRSC and NRCC—filed the challenge in 2022, joined by then-Senator JD Vance and then-Rep. Steve Chabot. Their argument was straightforward: the First Amendment protects a party's right to advocate for its own candidates, and the caps made no sense when Super PACs already operate without spending limits. "It doesn't make any sense to think of a party as 'corrupting' its candidates," the Republicans argued, "because the very aim of a political party is to influence its candidate's stance."
The Biden-era FEC had defended the law. Once Trump returned to office, the agency flipped and joined the Republicans. The FEC hasn't even had a quorum since April 2025 and can't enforce anything. The court appointed outside counsel Roman Martinez to argue the other side. Martinez claimed lifting the caps effectively legalizes quid pro quo corruption.
The dissenting liberal justices agreed. Justice Sonia Sotomayor warned that every time the court interferes with congressional design, "we make matters worse." Justice Elena Kagan argued during December arguments that coordinated party spending "effectively functions as contributions to the candidate" and allows donors to end-run individual contribution caps.
But the majority wasn't buying it. Justice Samuel Alito called Citizens United "unfairly maligned" and said its effect was to "level the playing field" by expanding a right to spend freely that had previously belonged only to media companies. The New York Post framed the ruling as a "midterm win for GOP," noting the RNC's $125 million cash-on-hand dwarfing the DNC's $14.8 million. The Guardian called it the fall of "one of the last remaining barriers between wealthy donors sending unlimited funds to federal political candidates." NPR said parties now get "the best of both worlds."
Here's what the establishment framing buries: the caps hurt parties of both stripes. Even Democrats acknowledged the limits have weakened political parties in an era of unrestricted outside spending. Last year, coordinated party spending for Senate races ranged from just $127,200 in small states to under $4 million in California. For most House races, the cap was $63,600—rounding error in modern campaigns. Those numbers didn't keep incumbents up at night. They kept challengers from mounting serious fights.
The old system favored the incumbent class and the consultant industry that feeds on it. Super PACs and dark-money groups—unaccountable, uncoordinated, and often working at cross-purposes with the campaigns they nominally support—filled the void. Parties, the organizations voters actually join and identify with, were sidelined.
The question now is whether both parties adapt, or whether only the one with the cash advantage weaponizes the new landscape first.
